This Recommendation describes the procedures and criteria for the reservation, assignment and reclamation of E.164 country codes and associated Identi
12、fication Code (IC) assignments. The criteria and procedures are provided as a basis for the effective and efficient utilization of the available E.164 numbering resources. Such assignments require a collaborative effort between the TSB and the appropriate ITU-T Study Group to endeavour to ensure tha

E.190 and the numbering plan formats detailed in ITU-T Rec. E.164. While processing E.164 resource applications, any con
14、flicts between these Recommendations that are identified will be resolved by the following: Those statements contained in ITU-T Rec. E.190 take precedence over ITU-T Rec. E.164, and those statements contained in ITU-T Rec. E.164 take precedence over this Recommendation. The TSB assigns and reclaims
15、E.164 country codes for geographic areas, global services and for Networks. It is also responsible for the assignment and reclamation of Identification Codes (ICs) for Networks. The assignment of subsequent digits are normally not the purview of the ITU-T, but are the purview of the assignee. Howeve
16、r, there may be unique circumstances by which it is jointly agreed by the TSB and the appropriate ITU-T Study Group that subsequent digits are to be centrally administered, e.g., UIFNs.

17、ution 1 approval process. ii ITU-T Rec. E.164.1 (05/2006) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible f
18、or studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T stu
19、dy groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis
20、 with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory p
21、rovisions (to ensure e.g. interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of
22、 such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no pos
23、ition concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, prot
24、ected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. ITU 2006 All rights reserved.

This Recommendation describes the procedures and criteria for the reservation, assignment, and reclamation
31、 of E.164 country codes and associated Identification Code (IC) assignments. The criteria and procedures are provided as a basis for the effective and efficient utilization of the available E.164 numbering resources. Such assignments require a collaborative effort between the TSB and the appropriate
32、 ITU-T Study Group to endeavour to ensure that the assignments meet the needs of the telecommunication community.

While processing E.164 resource applications, any conflicts between these Recommendations that are identified will be resolved by the following: Those provisions contained in ITU-T Rec. E.190 take precedence over ITU-T Rec. E.164, and those provisions contained in ITU-T Rec. E.16
34、4 take precedence over this Recommendation. The TSB assigns and reclaims E.164 country codes for geographic areas, global services and for Networks. It is also responsible for the assignment and reclamation of Identification Codes (ICs) for Networks1. The assignment of subsequent digits is normally
35、not the purview of the ITU-T, but are the purview of the assignee.

47、on regulatory and legal requirements. 4.2 In view of the evolutionary nature of telecommunication services and networks, the country codes, the ICs, and the format of the subsequent digits following the IC should provide adequate capacity to accommodate current and future requirements. 4.3 All newly
48、 assigned country codes will be three digits in length, the maximum allowable under the existing numbering plan structure, as defined in ITU-T Rec. E.164. 4.4 Country codes should first be assigned from decade blocks with country codes already assigned until all codes in such decades are exhausted,
49、e.g., reserved or assigned. 4.5 The TSB will wait for a period of at least two years before reassigning a previously assigned country code unless a shorter time interval is mutually agreed by the previous code holder, the applicant, the TSB and so advised by the appropriate ITU-T Study Group. 4.6 Although there may be exceptions, the assignment of E.164 country codes in any one of the following categories is not intended to supplement assignments made in another of these categories: i) geographic areas; ii) global s
